▎ 摘　　要

NOVELTY - A metal coating comprises metal base layer (1), heat insulating layer (2), wave absorbing layer (3) and coating layer (4), where top part of base layer is provided with heat insulating layer comprising fatty rock silicon dioxide, graphene and adhesive, and wave absorbing layer. The top portion of the heat insulation layer is provided with a wave-absorbing layer. The raw materials of the wave absorbing layers comprises 60-85 pts. wt. fatty rock silicon dioxide, 18-45 pts. ferrite, 9-16 pts. carbon fiber and 2-5 pts. adhesive. The coating layer is arranged on the top of the surface of the top portion. USE - Fat rock silica-based metal coating used in military equipment. Uses include but are not limited to war car, tank, artillery and fighter missiles. ADVANTAGE - The fat rock silica-based metal coating used in military equipment has excellent water-proof, high-temperature resistance, sound absorbing and silencing performance, and is non-toxic and tasteless, and has good fireproof heat insulation effect. DESCRIPTION OF DRAWING(S) - The drawing shows an external structure schematic diagram of a fat rock silica-based metal coating used in military equipment. 1Metal base layer 2Heat insulating layer 3Wave absorbing layer 4Coating layer
